Hi everyone, the hot bath tap has become stiff and the water, obviously, isn't running particularly well! I know I need to change the valve/gland inside which is dead easy I know. Having checked before asking, I'm looking as screwfix, B&Q, Wickes etc and all of their replacements appear to be 1/2 inch, now I thought bath taps were 3/4 ... are 3/4 available or will the 1/2 inch fit? Thnaks in advance for such a silly question
